Upgrading Injectors Without Tune

[toan]

hey guys

just wondering because im upgrading to GTR injectors on my rb20det, is ok to run without a tune or would it flood the engine with fuel?

thanks

Wont work. Need a modified ecu to correct it to work properly.

Either PowerFC or get a base map loaded in if using nistune. Then drive to tuner to get a proper tune.

as above, won't work without some form of ecu alteration whethe it be full aftermarket ecu, piggy back or a nistune (my recommendation)

you may possibly get the car to run (doubt it though) and if you were it would be an absolute cop to drive
